Writing is a medium of human communication that represents language and
emotion through the inscription or recording of signs and symbols.
In most languages, writing is a complement to speech or spoken
language. Writing is not a language but a form of technology. Within
a language system, writing relies on many of the same structures as
speech, such as vocabulary, grammar and semantics, with the added
dependency of a system of signs or symbols, usually in the form of a
formal alphabet.

The result of writing is generally called text, and the recipient of
text is called a reader. Motivations for writing include
publication, storytelling, correspondence and diary. Writing has
been instrumental in keeping history, dissemination of knowledge
through the media and the formation of legal systems. It is also an
important medium of expressing oneself by way of written words as do
authors, poets and the like. - Wikipedia
